N2® wire ropes - beyond anything

KISWIRE has been manufacturing a special range of offshore ropes for the global market for decades. Today the company produces 140.000 metric tons of wire rope annually, 40 000 tons of which fnd its way into the offshore sector in the form of special, large diameter rope for cranes, winches, anchor lines, mooring systems, subsea hoisting and other demanding applications.

In the Autumn of 2012, a brand new wire rope plant in Johor on the

Malaysian coast has been taken into use. The plant is called NEPTUNE 2 – N2 for short. This new plant designs and produces 6 and 8 strand ropes as well as N2 multi strand, non-rotating ropes in diameters ranging from 50 to 180 mm. a wide variety of N2 rope types will be available, ® with features including zinc/aluminium coating (Alumar ), plastic infll, variable strand compaction, special lubricants, and more.
